The /api/v3/exchangeInfo returns the following rate limits
Binance documentation says:
Endpoints related to /api/*:
- According to the two modes of IP and UID (account) limit, each are independent.
 - Endpoints share the 1200 per minute limit based on IP, excluding the new order endpoint POST /api/v3/order which has specific limits of 50 per 10 seconds and 160000 per day based on UID.
 - Responses contain the header X-MBX-USED-WEIGHT-(intervalNum)(intervalLetter), defining the weight used by the current IP.
 - Successful order responses contain the header X-MBX-ORDER-COUNT-(intervalNum)(intervalLetter), defining the order limit used by the UID.
 
So headers start with X-MBX-USED-WEIGHT- are related to rateLimits[0], headers start with X-MBX-ORDER-COUNT- are related to rateLimits[1] and rateLimits[2].
What about rateLimits[3]? How do I implement it?
